A twelve-year-old girl, orphaned after her parents die, grows up at a Swiss boarding school where she copes with loneliness, small humiliations, and a vivid inner life. She forges friendships and invents imaginative romances, then spends time among mountain folk in a châlet, learning local stories and practical skills. Encounters with a mysterious elderly woman and a sudden crisis force her to confront loyalty, identity, and courage. The narrative traces everyday schoolroom life, alpine adventures, domestic details, and moral choices, culminating in reconciliations and a public reckoning that marks her passage toward maturity.
